## What is OSAMERU?

Gave up on expense trackers? You can still stop overspending.
With OSAMERU, you just log what you spend, and see what's left in each category right away.

Dining out: 200 a month. Clothes: 800 a year. Household: 40 a week. For each category, choose an amount and how often it refills. Every time you log spending, what's left goes down right away, so you always know how much you can still spend.
